my acc is still locked
they just say that my id-card valid until 10.2019 is not accepted
my unlimited valid driver's license will not be accepted because it has expired
There are some forum members experienced the same what happened to your account and until now no news that they solve their issue.
What I notice here they are just collecting important documents like driver's license and after a few weeks or months, your account will be frozen then they tell the other client that their account is compromised.
Just keep contacting them not directly from Poloniex support but you must be contacting them via twitter and reddit because I heard if you keep sending the ticket via their website you will never solve your issue.
